No
The submission is solely for adding MR Conditional information to the labeling of existing predicate devices. The device description explicitly states that no other aspects, including design and performance, are impacted. There is no mention of AI or ML in the document.
Yes
The device is a joint replacement system indicated for treating various painful and disabling joint conditions (osteoarthritis, fractures, etc.), which directly addresses and alleviates a medical condition, qualifying it as a therapeutic device.
No
The device described is a total shoulder system, a reverse shoulder system, and radial head systems, which are joint replacement implants. Their intended use is for surgical replacement of joints, not for diagnosing conditions. The document mentions MRI testing to determine if the devices are MR Conditional, which relates to their safety in an MRI environment, not their diagnostic capability.
No
The device description explicitly states the submission is for adding MR Conditional information to the labeling of existing predicate devices, which are described as total shoulder systems, reverse shoulder systems, and radial head systems. These are clearly hardware implants. The submission focuses on testing the interaction of these hardware devices with MRI, not on a software component.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The intended use clearly describes the devices as implants for replacing or resurfacing joints (shoulder and elbow) due to various conditions like arthritis, fractures, and deformities. This is a therapeutic purpose, not a diagnostic one.
- Device Description: The description focuses on the physical characteristics of the implants and the addition of MR Conditional information to the labeling. It does not mention any components or functions related to testing samples from the human body for diagnostic purposes.
- Performance Studies: The performance studies described are related to the safety of the implants in an MRI environment (displacement, torque, heating, artifact). These are relevant to the physical device and its interaction with external forces, not to in vitro diagnostic testing.
IVD devices are used to examine specimens from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening. The devices described here are surgically implanted to treat musculoskeletal conditions.
N/A
Intended Use / Indications for Use
- The TITAN Modular Total Shoulder System is indicated for use as a hemi or total shoulder replacement for:
Severely painful and/or disabled joint resulting from osteoarthritis, traumatic arthritis or rheumatoid arthritis.Fracture-dislocations of the proximal humerus where the articular surface is severely comminuted, separated from its blood supply or where the surgeon's experience indicates that alternative methods of treatment are unsatisfactory.Other difficult clinical problems where shoulder arthrodesis or resection arthroplasty are not acceptable (e.g., revision of a failed primary component).Shoulder Hemiarthroplasty is also indicated for:
Ununited humeral head fractures.Avascular necrosis of the humeral head.Rotator cuff arthropathy.Deformity and/or limited motion.The humeral component is intended for cemented or uncemented use. The glenoid component is intended for cemented use only. - The TITAN Reverse Shoulder System is indicated for use in a grossly deficient rotator cuff joint with severe arthropathy or a previously failed joint replacement with a grossly deficient rotator cuff joint. The patient's joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device. The Titan Reverse Shoulder System is indicated for primary, fractures including proximal humeral, or revision total shoulder replacement for the relief of pain and significant disability due to gross rotator cuff deficiency. The glenoid baseplate is intended for cementless application with the addition of screws for fixation. The humeral stem is indicated for cemented or uncemented use and the humeral body component is intended for cementless use.
- The Ascension HRA System is intended for resurfacing of the humeral head due to:
Patients disabled by either non-inflammatory or inflammatory arthritis (i.e., rheumatoid arthritis, osteoarthritis and avascular necrosis)Mild or moderate humeral head deformity and/or limited motionPost-traumatic arthritisMalunions of the humeral headAcute fractures of the humeral headPatients with an intact or reparable rotator cuffContraindications:
Infection, sepsis, and osteomyelitisOsteoporosisMetabolic disorders which may impair bone formationOsteomalaciaRapid joint destruction, marked bone loss or bone resorption apparent on roentgenogramRevision procedures where other devices or treatments have failed4. The Ascension Modular Radial Head is intended for:
Replacement of the radial head for degenerative or post-traumatic disabilities presenting pain, crepitation, and decreased motion at the radio-humeral and/or proximal radio-ulnar joint with:
- joint destruction or subluxation visible on x-ray
- resistance to conservative treatmentPrimary replacement after fracture of the radial headSymptomatic sequelae after radial head resectionRevision following failed radial head arthroplasty5. The Katalyst Radial Head system is generally indicated for use in radial head replacement arthroplasty.
Use of the implant is contraindicated in those cases where complete avascular necrosis has rendered bone stock inadequate.

Dear Stephanie Rincones:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
